DAIDO Internal gear pump

Patent---Taocloid gear is a new technology created and developed by Daido

  • Reduce slippage between gears.
  • There is less vibration when liquid flows.
  • High speed, low noise and less vibration.
DAIDO internal rotating gear pump
DAIDO internal rotating gear pump

The entire impeller structure is composed of a large gear and a small gear. The large gear is fixed and rotates through the main transmission shaft; while the small gear is moved by the large gear through gear washers and pins. The center points of the large and small gears are centrifugally connected to each other. There is a crescent above the turntable, which runs between the external circle of the small gear and the internal circle of the large gear.

DAIDO內轉式齒輪泵浦

The large gear on the transmission shaft drives the small gear to rotate together. The small gear operates inside the crescent through the washer (bearing), and the large gear runs outside the crescent. Through this operation process, the fluid is transferred to the discharge port.
